Abstract
Abstract An apparatus for stabilizing the sway of an auto body that is mounted on coil springs by stabilizing the resilient movement of the coil springs and providing, in addition, means to restore the degree of lift of each spring and permit a balanced setting of the auto body, in which spacer blocks are positioned between coils of the spring and further in which each spacer block is extended to be fitted about at least three coils of said spring to retain those coils in alignment.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
92 words
In combination, a coil spring for an automobile and a stabilizing and spacing block to be fitted between coils of said spring and to grip a plurality of coils in which said spacing block is provided with one convolution coil receiving socket and an extended body having a curved portion to be hooked about a convolution of said coil that is not being spaced to maintain all coils in alignment and in which said spacing portion of said block abuts with a third coil to restore the desired lift to said spring.
Claim 2
Dependent Claim
92 words
In combination, a coil spring for an automobile and a stabilizing and spacing block to be fitted between coils of said spring and to grip a plurality of coils in which said spacing block is provided with one convolution coil receiving socket and an extended body having a curved portion to be hooked about a convolution of said coil that is not being spaced to maintain all coils in alignment and in which said spacing portion of said block abuts with a third coil to restore the desired lift to said spring.
Claim 3
Dependent Claim
39 words
In a device according to claim 1 in which the abutting portion of said spacing portion of said block that abuts with said third convolution is formed with a half-round groove to follow the radius of the coil spring.
Claim 4
Dependent Claim
26 words
In a device according to claim 1 in which the stabilizing and spacing blocks are mounted both externally and internally to the convolutions of the spring.
Claim 5
Dependent Claim
34 words
In a device according to claim 1 in which the abutting portion of said spacing portion of said block that abuts with said third convolution is centrally positioned in said stabilizing and spacing block.
Claim 6
Dependent Claim
61 words
In combination, a coil spring for an automobile and a pair of stabilizing and spacing blocks to be fitted one inside said coils and one outside said coils of said spring and each block to grip three or more of the coils and in which each spacing block is provided with one spacing portion and extended body to grip other convolutions.
Claim 7
Dependent Claim
61 words
In combination, a coil spring for an automobile and a pair of stabilizing and spacing blocks to be fitted one inside said coils and one outside said coils of said spring and each block to grip three or more of the coils and in which each spacing block is provided with one spacing portion and extended body to grip other convolutions.
Claim 8
Dependent Claim
27 words
In a device according to claim 5 in which the extended body grips a convolution that is not being spaced to retain said coil spring in alignment.
Claim 9
Dependent Claim
26 words
In a device according to claim 5 in which the extended body grips convolutions that are not being spaced to retain said coil spring in alignment.
Claim 10
Dependent Claim
33 words
In a device according to claim 5 in which the extended body grips a convolution either side of said spacing portion that is not being spaced to retain said coil spring in alignment.
